The Effect of Geometry on the Stress Behavior of Flexible Tube with the Lateral Deflection

Abstract

As analysis research, the effect of boundary condition combination of the stress of the automobile flexible tube has been proposed in this paper. FEM solution for a Ω-shaped flexible tube under the action of lateral deflection and angle of rotation are obtained. The research shows the fact that the maximum von-Mises stress decreases to minimum value and the stress exhibit an upward trend after the minimum stress with the increase of the lateral deflection or the angle of rotation. Furthermore, an important suggestion should be made that the maximum von-Mises stress becomes minimum on the condition of lateral deflection (mm) /angle of rotation (degree) =10.
